Throttle Position Sensor for 2007 Silverado
I've been getting a check engine light. My FIXD OBD-II Active Car Health Monitor was showing a P0121 code and says it's a serious problem. I replaced my throttle position sensor with a Duralast TPS4270 from Autozone. Now the engine idles between 2000 and 2500 RPMs. Prior to replacing the sensor the truck was running perfect with the exception of the check engine light. Any suggestions?

Relearn procedure:
After I posted this question here I found this video on youtube. What did I ever do without youtube! Apparently it takes a while for the truck's computer to relearn the position of the throttle.(When I replaced the sensor I cleaned the carbon buildup off the throttle body. Made it shine like new!) After trying the 3 minute idle, 1 minute off, 3 minute idle procedure several times and driving it around over 44 mph several times with no success, I let it sit over night and the problem fixed itself. Wish all my mechanical problems resolved themselves that way.
